METAL   BACK  BRUSHES

STRAIGHT  STRIP		COILED  STRIP

Metal back brushes are available in straight strips and coiled.   Coils are available in open style ( as above ) or closed face, with the coils next to each other. 

Straight strips are held in place by special holders.  Coiled brushes are put on a metal shaft that turn due to mechanization.  These are normally used to clean conveyors or items moving past the brush.

These brushes are made by putting bristles into a metal channel and folding it tight on the bristles, holding them in place.  The size of the metal back is important to the construction of the brush.
